Flame retardant and dielectric properties of glass fibre reinforced nylon-66 filled with red phosphorous

摘要

Incorporation of red phosphorous into glass fibre reinforced nylon-66 composites not only confers good fire retardancy but also retains good dielectric properties, that makes them suitable for application as electrical insulation components. The limiting oxygen index(LOI)and Underwriter's Laboratory Bulletin 94(UL-94)flame retardancy rating of the red phosphorous filled nylon-66 composites increase consistently with their red phosphorous contents. However, the arc resistance and dielectric strength were found to decrease as the phosphorous contents increased.
